i am seeing similar behavior on my machine (also 64-bit ubuntu, but
version 8.10 instead of 9.10).
when i run sudo god -c god_config.god, htop sees two two god processes
starting up and thus two processes for each watch specified in the
config file. i wonder if these are related issues.
that being said, and i am new to god, i'm wondering if your config
file is what's causing the process not to be killed.
w.start = "/usr/local/ruby/bin/ruby /home/xman/code/test.rb"
w.restart = "#{w.start}"
given these commands if you issue sudo god restart jruby-test, it will
just start up a new process for test.rb. it should still work if you
issue it a stop and then start command individually though.
here's the config file i'm using:
RAILS_ROOT = File.dirname(File.dirname(__FILE__))
def generic_monitoring(w, options = {})
w.start_if do |start|
start.condition(:process_running) do |c|
c.interval = 10.seconds
c.running = false
end
end
w.restart_if do |restart|
restart.condition(:memory_usage) do |c|
c.above = options[:memory_limit]
c.times = [3, 5] # 3 out of 5 intervals
end
end
w.lifecycle do |on|
on.condition(:flapping) do |c|
c.to_state = [:start, :restart]
c.times = 5
c.within = 5.minute
c.transition = :unmonitored
c.retry_in = 10.minutes
c.retry_times = 5
c.retry_within = 2.hours
c.notify = {:contacts => 'support'}
end
end
w.transition(:up, :start) do |on|
on.condition(:process_exits) do |c|
c.notify = {:contacts => 'support'}
end
end
end
God.watch do |w|
script = "#{RAILS_ROOT}/app/background/finished_waves_checker.rb"
w.name = "finished_waves_checker"
w.group = "wave_processors"
w.interval = 60.seconds
w.start = "#{RAILS_ROOT}/script/runner #{script}"
w.start_grace = 20.seconds
w.restart_grace = 20.seconds
w.behavior(:clean_pid_file)
generic_monitoring(w, :memory_limit => 100.megabytes)
end
5.times do |i|
God.watch do |w|
script = "#{RAILS_ROOT}/app/background/background_matcher.rb"
w.name = "background_matcher_#{i.to_s}"
w.group = "wave_processors"
w.interval = 60.seconds
w.start = "#{RAILS_ROOT}/script/runner #{script}"
w.start_grace = 20.seconds
w.restart_grace = 20.seconds
w.behavior(:clean_pid_file)
generic_monitoring(w, :memory_limit => 100.megabytes)
end
end
God.watch do |w|
script = "#{RAILS_ROOT}/app/background/printed_queue_checker.rb"
w.name = "kiosk-notification-checker"
w.group = "wave_processors"
w.interval = 60.seconds
w.start = "#{RAILS_ROOT}/script/runner #{script}"
w.start_grace = 20.seconds
w.restart_grace = 20.seconds
w.behavior(:clean_pid_file)
generic_monitoring(w, :memory_limit => 100.megabytes)
end
any help appreciated.
